一种共享磁通多耦合模式的无线电能传输系统抗偏移方法

A method for integrating a reversed-polarity concentric compensating inductor based on the LCC topology is proposed from the perspective of shared flux, then two integrated structures are proposed. A mathematical model of the output power and transmission efficiency of the reversed-polarity concentric wireless power transmission system based on the multi-coupling mode of operation and the quality factor of the coil is developed, and the offset resistance of the integrated structure is verified from the mathematical model. The simulation results show that the integrated structure outperforms the non-integrated structure in terms of flux density in both forward and offset cases. The experimental prototype of the compensated inductor integrated structure is built. The experimental results show that the compensated inductor integrated structure can maintain stable transmission efficiency and output power within a certain offset range, and has higher transmission efficiency and higher transmission power than the non-integrated structure at the same input voltage and transmission distance.
